FIG-2 United States Patent Oice 2,712,333 CHERRY-PITTNG MACHINE om Toyota Hirao, Paseo, Wash. Appiication ctober 24, 1952, SerialNo. 316,677 1 Claim. (Cl. 146-19) This invention It is one object which is well adapted for removing the pits from a large number of cherries.

Another a cherry-plttlng machine which Another object of the invention lies in the provision of a cherry-pitting machine having a longitudinally inclined table,

Another object of of a cherry-pitting which has depressed the sockets which hold the cherries removed.

the invention lies in the provision machine having an inclined table while the pit is being rounded by a stripping bar which permits removal of the cherries from the plungers.

These and other objects of apparent during the course of the invention will become the following description. part of this to designate like parts,

Figure 1 is a perspective view of my improved cherrypitting machine; and

Figure 2 is a longitudinal vertical cross section taken through the machine.

Referring now more indicate the table of the machine tracks leading from its hopper to 2,712,333 Patented July 5, 1955 the ends of reenforcing rail 16; This a sturdy machine which is not liable to 14, table 10` and provides for be broken.

aperture 22. Pivotally the ends of the stripping bar 21 is a U- shaped guide yoke 25. This is provided to guide the movement of plunger bar 23 ment away from down tracks he hopper,

To assist in displacing the cherries C from the sockets 28, I have provided a lifter bar 3l) which` carries a lifter disposed axially aligned plunger and an aperture 27, forming a bank of relation with the plunger table and the lifter bar below the table. As plunger bar 23 is moved downwardly, lifter bar 30 is simultaneously moved downwardly, and the bars are moved upwardly simultaneously, thus forming a vertically shiftis secured at its ends to the lever 20 SOIR@- times bouncing and rolling on down the inclined table;

in the sockets, the

them out of the sockets permitting them to roll down the inclined table. It will be noted face of each plunger is serrated to provide means of holding the pit against slipping from beneath the plungers.

Locking strips 36 are pivoted at 37 to the inner face of side rails i4 and are provided with an enlarged head portion 38 adapted to be swung between stripping bar 21 and plunger bar 23 to maintain the plungers 24 in their raised position. Of course, whilethe lifter bars 31 are extended into the sockets 28, any cherry rolling down the tracks 29 will impinge against the litters and then as the downward movement is made will be permitted to roll into the sockets 28.

For cleaning purposes, it is only necessary to remove the upper or lower ends of the securing strips 32 and pivot the yokes 2S out of confining relation to plunger bar 23 and the plunger bar and its plungers are separated from the table, as also is the lifter bar and its plungers. The plunger bar may be slid over the grip 34 of the lever 20 and the various parts cleaned and reassembled.

Having thus described my invention, I claim:

A cherry-pitting machine comprising in combination a table inclined longitudinally, a transversely disposed row of spaced socketsin the upper face of said table, each said socket having an aperture extending downwardly through the table, depressed tracks on the upper face of said table and communicating one with each said socket and extending longitudinally of the table upwardly of the sockets, a stripping bar disposed spaced above said sockets and having apertures axially aligned with said `lirst named apertures, a plunger bar parallel with and above said stripping bar and shiftable toward and away from said stripping bar, depending plungers carried by said plunger bar and extending axially through said second named apertures and normally spaced above said first named apertures, whereby of said plunger bar will effect movement of the lower ends of said plungers through said sockets and into said first named apertures, a litter bar disposed beneath the table parallel with said plunger bar and shiftable therewith toward and away from the table, upstanding lifters carried by said lifter bar and axially aligned with said plungers and adapted to move upwardly through said first named apertures into said sockets, said litters having angled faces disposed at an angle greater than the ineline of said table and in the same direction, whereby cherries in the sockets are displaced, and a tilta'ole lever hingedly carried by the table and operably connected to said plunger bar whereby said plunger bar may be manually shifted in a vertical path.
